The fMAX you will get will also depend on the number of peripherals and the structure of the Avalon bus, because the Avalon bus arbitration can become a bottleneck if you are not careful. You can speed things up by putting non-performance critical peripherals behind a bridge. I think there is discussion of this at the end of the Nios II Handbook.
